If you want a wooden chopping board to last 5 to 10 years instead of just 12 to 18 months, you need to oil it regularly because wood loses moisture, dries out and cracks without a protective food safe oil barrier.
Why do wooden cutting boards need oiling?
Wood is a natural, porous material. Every time you wash your board, water and detergents draw oils out of the fibres. Without replacing those oils, the board starts to dry, warp and split. Oiling does three essential jobs:
- Prevents cracking and warping: A well oiled board is less likely to cup or split, even at sizes like 45x35cm where movement can be more dramatic.
- Reduces stains and smells: Oil fills the pores so beetroot, curry and onion juices sit on the surface instead of soaking deep into the grain.
- Improves food hygiene: A smooth, sealed surface is easier to scrub clean. Bacteria find it harder to settle into tiny dry cracks.
This is why every Deer & Oak board, from our 1.2kg Medium Bamboo to our 2.1kg Large Acacia, arrives pre oiled and ready to use. Regular top ups at home then keep that protection going.
What happens if you do not oil a wooden board?
Skip the oil for a few months and your board starts to tell on you. The signs usually appear in this order:
- Dry, rough surface: The top feels fuzzy and grey rather than rich and smooth. This can happen within 4 to 6 weeks on a heavily used board.
- Raised grain and knife drag: Your knife no longer glides. Instead it catches on tiny lifted fibres, which makes chopping less precise.
- Small cracks and cupping: A 45x35cm board can start to bow by 2 to 3 mm across its width if one side dries faster than the other.
- Deep staining and odour: Liquids soak straight in, leaving permanent dark patches and lingering smells.
Once cracks appear, there is no way to fully repair the structure of the wood at home. Regular oiling costs only a few minutes each month and can easily double or triple the working life of a board.
How often should you oil a wooden cutting board?
For most home kitchens, a simple rule works well:
- First month: Oil once a week while the board settles into your kitchen environment.
- After that: Oil every 3 to 4 weeks, or any time the surface looks pale, feels dry or water stops beading on top.
Heavy use, such as daily family cooking or professional prep, may need oiling every 2 weeks. A larger, heavier board like the 2.1kg Deer & Oak Large Acacia tends to hold oil slightly longer than a lighter 1.2kg Medium Bamboo board, but both benefit from a regular routine.
What oil should you use on wooden boards?
Always choose a food safe, non rancid oil. At Deer & Oak we pre treat our boards with food grade mineral oil and natural waxes because they stay stable for years.
Suitable options:
- Food grade mineral oil
- Specialist cutting board oil and wax blends
- Cold pressed fractionated coconut oil (non solidifying type)
Avoid:
- Olive oil, sunflower oil or rapeseed oil, as they can turn sticky and rancid
- Flavoured oils that may taint food
- Varnish or furniture polish that is not food safe
Our pre oiled carbonised bamboo board and acacia sets arrive with this protective finish already in place, so you simply maintain it at home.
Simple step by step: how to oil your wooden cutting board
Here is a practical routine that works on both bamboo and hardwood boards, including the Deer & Oak range:
- Clean first: Wash the board with warm water and a small amount of mild washing up liquid. Rinse well.
- Dry completely: Stand the board on its side to air dry for at least 8 to 12 hours. Oiling a damp board traps moisture inside.
- Apply oil: Pour about 1 to 2 tablespoons of oil onto a 45x35cm board, or 1 tablespoon for a 38x28cm board. Spread with a lint free cloth in the direction of the grain.
- Cover every surface: Do both faces, all four edges and any juice grooves. Pay extra attention to the end grain, which is more absorbent.
- Let it soak: Leave the board flat for 20 to 30 minutes. If dry patches appear, add a few more drops.
- Buff off excess: Wipe away any oil that has not soaked in with a clean cloth until the surface feels dry and silky, not greasy.
For wax finishes, apply a thin layer after oiling, wait 15 to 20 minutes, then buff until the board has a soft sheen.
Does bamboo need oiling as well as hardwood?
Yes. Bamboo is technically a grass, but high quality boards behave very much like hardwood. Our Moso bamboo boards are dense and strong, yet the cut fibres still lose moisture over time.
On a 45x35cm Large Bamboo Board that weighs 1.8kg, the surface area is big enough that uneven drying can cause slight cupping if left untreated. Regular oiling keeps both sides balanced and stable. Carbonised bamboo, such as our 1.9kg Carbonised Bamboo Board, benefits even more because the heat treatment that gives it a darker tone also opens up the fibres slightly.

Who this is for and who it is not for
Ideal for:
- Home cooks who want a board to last 5 to 10 years with simple monthly care
- People who prefer natural materials like Moso bamboo and acacia over plastic
- Anyone who chops daily and wants a stable, knife friendly surface from 38x28cm up to 45x35cm
- Hosts who use boards as serving platters for cheese, bread and charcuterie
Not recommended for:
- People who put boards in the dishwasher or soak them for long periods
- Those who never want to oil or maintain their kitchenware at all
- Very high volume commercial kitchens that need heavy industrial plastic boards
- Anyone with no worktop space for a 45x35cm board and who prefers small flexible mats
Frequently asked questions
Q: How do I know when my wooden cutting board needs oiling?
A: Look for pale, dry looking patches, a rough feel or water that no longer beads on the surface. If a drop of water sinks in within 30 seconds instead of sitting on top, it is time to oil. Many people find every 3 to 4 weeks is enough for daily home use.
Q: Can I use olive oil or vegetable oil on my cutting board?
A: It is better not to. Oils like olive, sunflower and vegetable oil can turn sticky and rancid over time, which can cause smells and discolouration. A food grade mineral oil or specialist board oil stays stable and keeps the wood protected without spoiling.
Q: Do pre oiled boards still need maintenance?
A: Yes, but less often at the start. Deer & Oak boards arrive pre oiled so you can use them straight away, then you simply top up the finish as it gradually wears. For most people this means a light oil after the first month, then every few weeks depending on use.
Q: Will oiling make my board waterproof?
A: Oiling makes the board water resistant, not fully waterproof. It slows down how quickly moisture gets in and makes cleaning easier, but you should still avoid soaking or dishwashing. A quick wash, thorough dry and regular oil keep the wood in good condition.
Choosing the right Deer & Oak board for you
If you are looking for the best wooden cutting board for everyday family cooking and you are happy to oil it monthly, our Bamboo Double Pack (DNO-BCB-2PK) is a very practical place to start. You get a 45x35cm board for bread, roasts and large prep, plus a 38x28cm board for fruit, herbs and smaller tasks, together weighing 3.0kg so they feel steady and secure on the worktop. You can find that set on Amazon UK or browse all boards on our Deer & Oak chopping board collection.
If you prefer a richer wood grain and a slightly heavier feel under the knife, the Large Acacia Board (DNO-ACB-LG) at 45x35cm and 2.1kg is a strong choice. It arrives pre oiled, so your only job is to refresh the oil every few weeks. You can see our acacia range on Amazon or explore our current bestsellers on the Deer & Oak shop.
Whichever board you choose, a few minutes with a bottle of oil each month is the small habit that keeps it looking good, feeling smooth and working hard beside your hob year after year.
